get the truck.... its still under warranty.. when you get it back drive the $hit out of it... helps blow all the crap out/off the egr. "Drive it like you stole it" at least once a week. check your deltas from your ECT & EOT should be under 15*..... Then check when your warranty is up and plug the oil cooler kill the egr cooler and blow the turbo..... and get it fixed under warranty with ARP bolts.....
